Abstract (en)
[origin: EP3748304A1] Apparatuses and sensor systems are described with magnetoresistive sensor configurations. The method of detecting a displacement of a magnetic component includes monitoring, via a position sensor operating in a low-powered mode, a magnetic field emitted by a magnetic component. The monitored characteristics of the magnetic field vary based at least in part on a displacement of the magnetic component. The method also includes determining, via the position sensor, whether the monitored characteristics of the magnetic field satisfy an activation criteria. The method further includes increasing the power of the position sensor to a high-powered mode to determine the displacement of the magnetic component upon determining that the monitored characteristics of the magnetic field satisfy the activation criteria. Corresponding position sensing systems are also provided.
